Will do, may take a day or two, not a keen user of technology, prefer gardening, but will get back, you all have been very patient, I'm grateful, why chuck out decent kit when it still does the job.

Okay, with history deleted and just the settings tab, this is what Opera Task Manager is showing:
BROWSER 38,172KB
GPU PROCESS 17,740KB
UTILITY: NETWORK SERVICE 14,080KB
UTILITY: AUDIO SERVICE 5,844KB
TAB: SPEED DIAL 23,620KB
TAB: SETTINGS 46,228KB
EXTENSIONS: VIDEO HANDLER 16,984KB
EXTENSIONS: BACKGROUND WORKER 21,456KB

@blackbird71
...I think so, I usually do it as a matter of course whenever I finish, but not totally sure this time. Right now the notebook is updating, I will try again tomorrow and get back to you.

@blackbird71
Okay. Done everything. Usage is now 244Mb with just the Opera settings tab open. Is that within acceptable limits?

@elpocito
Oops, meant to say there is no folder called "AppData". Could it be hidden? I tried to create one with that name and it said it was already in use, way back to 2011.

@nvmjustagirl
Have no idea what a "page file" is, certainly have changed anything.

@burnout426
Thanks, it was on, turned it off.

@blackbird71
The path for the profile is c:\Users\netbook\AppData\Roaming\Opera Software\Opera Stable. I tried file explorer but it couldn't find it. I then tried going backwards through each folder, got as far as "netbook' but there is folder called AppData.

No extensions. I opened the Opera Task Manager and there's about 700Mb of activity there with just Yahoo Mail open in one tab, so I see what you mean about reaching my limit on RAM, will have to upgrade the notebook (nine years old) for something more appropriate. Thanks for your help and clear explanation, much appreciated.
